1. Summary:
Updated kernel packages that fix several security issues and bugs in the
Red Hat Enterprise Linux 4 kernel are now available.
This security advisory has been rated as having important security impact
by the Red Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, noarch, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, noarch, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, noarch, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, noarch, x86_64
3. Problem description:
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the security issues described
below:
* a flaw in the connection tracking support for SCTP that allowed a remote
user to cause a denial of service by dereferencing a NULL pointer.
(CVE-2007-2876, Important)
* a flaw in the mount handling routine for 64-bit systems that allowed a
local user to cause denial of service (crash). (CVE-2006-7203, Important)
* a flaw in the IPv4 forwarding base that allowed a local user to cause an
out-of-bounds access. (CVE-2007-2172, Important)
* a flaw in the PPP over Ethernet implementation that allowed a local user
to cause a denial of service (memory consumption) by creating a socket
using connect and then releasing it before the PPPIOCGCHAN ioctl has been
called. (CVE-2007-2525, Important)
* a flaw in the fput ioctl handling of 32-bit applications running on
64-bit platforms that allowed a local user to cause a denial of service
(panic). (CVE-2007-0773, Important)
* a flaw in the NFS locking daemon that allowed a local user to cause
denial of service (deadlock). (CVE-2006-5158, Moderate)
* a flaw in the sysfs_readdir function that allowed a local user to cause a
denial of service by dereferencing a NULL pointer. (CVE-2007-3104, Moderate)
* a flaw in the core-dump handling that allowed a local user to create core
dumps from unreadable binaries via PT_INTERP. (CVE-2007-0958, Low)
* a flaw in the Bluetooth subsystem that allowed a local user to trigger an
information leak. (CVE-2007-1353, Low)
In addition, the following bugs were addressed:
* the NFS could recurse on the same spinlock. Also, NFS, under certain
conditions, did not completely clean up Posix locks on a file close,
leading to mount failures.
* the 32bit compatibility didn't return to userspace correct values for the
rt_sigtimedwait system call.
* the count for unused inodes could be incorrect at times, resulting in
dirty data not being written to disk in a timely manner.
* the cciss driver had an incorrect disk size calculation (off-by-one
error) which prevented disk dumps.
Red Hat would like to thank Ilja van Sprundel and the OpenVZ Linux kernel
team for reporting issues fixed in this erratum.
All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels
to the packages associated with their machine architectures and
configurations as listed in this erratum.
